            <?php  } ?>
        </td>
    <?php endforeach; ?>

$_item->getOptionByCode('additional_options') this lines returns empty array .Please someone guide me hoe to get the additional option value .I have seen the quote_item_option table it contains the data . I have added custom options to quote item using below code

        $quote = $this->quoteFactory->create()->load($quoteId);
        $_product = $this->product->load($productId);
        $additionalOptions = array();
            if ($additionalOption = $_product->getOptionByCode('additional_options')) {
                $additionalOptions = $this->serializer->unserialize($additionalOption->getValue());
            }

            $additionalOptions[] = [
                'label' => 'Type',
                'value' => 'Sample'
            ];
        $quote->addProduct($_product, 1)
                    ->addOption(array(
                        'product_id' => $_product->getId(),
                        'code' => 'additional_options',
                        'value' => $this->serializer->serialize($additionalOptions)
                    ))
                    ->setCustomPrice(2)
                    ->setWeight(5)
                    ->setOriginalCustomPrice(2)
                    ->getProduct()->setIsSuperMode(true);
                $quote->collectTotals()->save();

We need to create a plugin for the retrieve custom option from the cart to order.

First We need to create di.xml.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Quote\Model\Quote\Item\ToOrderItem">
        <plugin name="unique_name" type="Vendor\Module\Model\Plugin\Quote\ToOrderItem" sortOrder="1" />
    </type>
</config>

Once you have created this file, now you need to create another file and named as CompanyName\ModuleName\Model\Plugin\Quote\ToOrderItem.php

<?php
namespace Vendor\Module\Model\Plugin\Quote;

use Magento\Quote\Model\Quote\Item\ToOrderItem as QuoteToOrderItem;
use Magento\Framework\Serialize\Serializer\Json;
class ToOrderItem
{    
    public function __construct(Json $serializer = null) 
    {        
        $this->serializer = $serializer ?: \Magento\Framework\App\ObjectManager::getInstance()
            ->get(\Magento\Framework\Serialize\Serializer\Json::class);
    }

    public function aroundConvert(QuoteToOrderItem $subject,
        \Closure $proceed,
        $item,
        $data = []
    ) {
        // Get Order Item
        $orderItem = $proceed($item, $data);               
                
        $additionalOptions = $item->getOptionByCode('additional_options');        
        // Check if there is any additional options in Quote Item                    
        if (count($additionalOptions) > 0) {
            // Get Order Item's other options
            $options = $orderItem->getProductOptions();
            // Set additional options to Order Item
            $options['additional_options'] = $this->serializer->unserialize($additionalOptions->getValue());
            $orderItem->setProductOptions($options);
        }
 
        return $orderItem;
    }
}
